• DBMS agnostic - What to name the COUNT column from a SQL Query

  - by cyberkiwi

  I have trouble naming the COUNT() column from SQL queries and will swap between various variants _Count [Count] (sql, or "count" or backticks for MySQL etc) C Cnt CountSomething (where "something" is the field being counted, or "CountAll") NoOfRows RowCount etc Has anyone come up with any name that you are happy with and always use without hesitation? This is bothering me because after joining SO just recently, my answers have shown this tendency of flip-flopping with no consistency. I need to get this sorted. Please help. (While we're at it, what do you use for SUM etc?) Note: Before you close this question, consider that this one was not: What's the best name for a non-mutating “add” method on an immutable collection?

• Is there any text editor for windows which can save files with code highlight for viewing

  - by user1713836

  I want some software for Windows where I can save code snippets and other daily usable commands in one file. Everyday I find some small code snippets which I want to save in a single file. Just like we have code snippet savers online, I want something offline on Windows, basically with all the features Microsoft Word has, but with code highlight. It should be lightweight like Notepad++. I mean if I select the code and then press some button, it should change the color according to the language. Currently I use Notepad++, but in it, I can't select small code snippets on one page. It either highlights the entire file or nothing.

• Career in Game Development

  - by cantbereached

  Hello, I currently study computer engineering and I want to lead my career towards game industry which I always want to be a part of. But I am not sure where to start. I applied some of the companies in the industry for internship and so but most of them wants experience and some work in game developing. Many asks whether I developed a simple game or something similar which I haven't done so far. I am proficient at C, C++, Java, JS, HTML etc. Any tips from people experienced in the industry on where to start ?

• Twig Code Completion

  - by Ondrej Brejla

  Hi all! After few weeks we have a new feature for you which will be available in upcoming NetBeans 7.3. It's about new code completion in Twig files! So let us introduce it a bit. Now we hopefully support all of Twig built-in elements. It means Tags, Filters, Functions, Tests and Operators (see Twig documentation for more information). All elements are also documented, so if you don't know what which element does, just read it in the IDE documentation window! We try to resolve some Completion Context to suggest you only the most corresponding element types, but it's not so visible, since almost everything can be used everywhere in Twig files ;) And that's all for today and as usual, please test it and if you find something strange, don't hesitate to file a new issue (product php, component Twig). Thanks a lot!

• Resources for up-to-date Delphi programming

  - by Dan Kelly

  I'm a developer in a small department and have been using Delphi for the last 10 years. Whilst I've tried to keep up-to-date with movements there are a lot of changes that have occurred between Delphi 7 and (current for us) 2010. Stack Exchange and here have been great for answering the "how do you" questions, but what I'd like is a resource that shows great examples of larger scale programming. For example is there anywhere that hosts examples of well written, multi form applications? Something that can be looked at as a whole to illustrate why things should be done a certain way?

• implementing match-making & community system for multiplayer games

  - by kamziro

  These days, games often have multiplayer portals with chat channels & match making system for the multiplayer aspects of the game. An example would be battle.net, magic the gathering online's chat rooms, halo etc. Now, for the rest of us indie gamers that probably won't be able to spend much development effort on creating those back-ends from scratch, what options do we have? I was thinking of something along the line of using IRC as the backbone of the system. From there, the "community" aspect and implement player tracking, game tracking and match making on top of that. It seems to be what the old battle.net (brood war era) used to be. The question is, is this easy to do? What does it take to run an irc server, and I suppose this also requires writing an IRC client (which seems to have been done a lot these days?)? If there are other ways as well (say, an open framework for this stuff), let's hear them too.

• Open Source Bulletin Board with Facebook Group Integration

  - by Brian

  I'm working on a an open-source community-oriented project which needs a highly social component where users can post discussion topics and questions and interact with each other. It would be ideal to facilitate discussion seamlessly between a bulletin board and Facebook. Has anyone seen such an integration? I'm talking about something that goes beyond a simple FB OAuth and actually synchronizes both forum posts / topics / OAuth / comments. Pretty please if a moderator is going to delete this tell me which StackExchange forum is the appropriate place for posting such an inquiry. :)

• Rationale behind freeware projects

  - by VexXtreme

  I've seen some freeware projects in the past where the author(s) invested a significant amount of their personal time and resources and never even considered charging for the software. A lot of these projects were donation based, and from what I've heard, donationware can never be a viable business model (even to simply support development costs) because most people choose not to donate if given an option. A lot of these projects eventually shut down because their authors could not sustain them further. Granted, some people simply like making the community happy (or something), but if you're struggling to keep your project alive, why not charge some small amount such as $10 simply to stay operational? If people find your software useful (and a lot of people found those projects VERY useful) they won't have a problem paying such a small amount. The question is: if you have a popular app that people like and download in great numbers, why not put a price tag on it? Why do it for free?

• Sending keyboard commands to Ubuntu through Python. Remote for my Blackberry

  - by Rudi Strydom

  I am trying to build a remote control application to control media on my Ubuntu. Does anyone know a way in order to accomplish this. The media keys in particular. Thank you. EDIT 1: I have tried using XTE, but is seems python in truncating the input or there is a limit or something which means that you can't do Ctrl + Key key presses, which wont suit my needs. I also tried uinput, but alas you need to run it as root, which also will not quite my needs. Now I am looking at EVDEV which seems promicing, that is if I can get it working.

• How does the GPL static vs. dynamic linking rule apply to interpreted languages?

  - by ekolis

  In my understanding, the GPL prohibits static linking from non-GPL code to GPL code, but permits dynamic linking from non-GPL code to GPL code. So which is it when the code in question is not linked at all because the code is written in an interpreted language (e.g. Perl)? It would seem to be too easy to exploit the rule if it was considered dynamic linking, but on the other hand, it would also seem to be impossible to legally reference GPL code from non-GPL code if it was considered static! Compiled languages at least have a distinction between static and dynamic linking, but when all "linking" is just running scripts, it's impossible to tell what the intent is without an explicit license! Or is my understanding of this issue incorrect, rendering the question moot? I've also heard of a "classpath exception" which involves dynamic linking; is that not part of the GPL but instead something that can be added on to it, so dynamic linking is only allowed when the license includes this exception?

• Cocos2d and Body with few collision shapes using chipmunk

  - by Eimantas

  I'm using Cocos2d (0.99.5) with chipmunk physics engine. Currently I'm trying to place a body into space which is combined from few circle shapes. Let's say I have a corresponding sprite image with displays atom (nucleus + 3 electrons around it. Something like this without orbit lines). In it's simplest form - only one circle shape at the center should be enough which would detect collisions from other objects with nucleus. Now I'd like to add other circle shapes for each electron. How can I do that? Now when I add those shapes to the body and add the body into chipmunk space - the shapes (together with the body/sprite) start flickering and spinning with no recognizable pattern (or reason for that matter).

• Login timeout disable?

  - by Sk606

  How can I disable automatic timeout entries in the login screen? Allow me to explain. My typical experience goes something like this: I put my laptop to sleep, then wake it. When it wakes, it comes up with the login screen. I type in my password and it will usually reject it, with a message indicating the login timer has expired. I then enter my password a second time and it logs in. Not the end of the world, but annoying nonetheless. Any suggestions?

• Incremental file system backups

  - by brunopereira81

  I use Virtual Box a lot for distro / applications testing purposes. One of the features I simply love about it is virtual machines snapshots, its saves a state of a virtual machine and is able to restore it to its former glory if something you did went wrong without any problems and without consuming your all hard disk space. On my live systems I know how to create a 1:1 image of the file system but all the solutions I'v known will create a new image of the complete file system. Are there any programs / file systems that are capable of taking a snapshot of a current file system, save it on another location but instead of making a complete new image it creates incremental backups? To easy describe what I want, it should be as dd images of a file system, but instead of only a full backup it would also create incremental. I am not looking for clonezilla, etc. It should run within the system itself with no (or almost none) intervention from the user, but contain all the data of the file systems.

• How should I pronounce the :: and -> in PHP?

  - by Renesis

  When I read these lines aloud to someone: $controller->process(); UserManager::getInstance(); How should the -> and :: be pronounced? Reading the characters themselves in cumbersome and I don't know of any nicknames for them. Being a developer who is used to C-style syntax, I'd like to say "dot", but I'd like something that is easy to say and people can easily understand. It would also be good to know if there are any pronunciations that have become de-facto standards among teams of developers.

• What is Object Oriented Programming ill-suited for?

  - by Richard JP Le Guen

  In Martin Fowler's book Refactoring, Fowler speaks of how when developers learn something new, they don't consider when it's inappropriate for the job: Ten years ago it was like that with objects. If someone asked me when not to use objects, it was hard to answer. [...] It was just that I didn't know what those limitations were, although I knew what the benefits were. Reading this, it occurred to me I don't know what the limitations or potential disadvantages of Object-Oriented Programming are. What are the limitations of Object Oriented Programming? When should one look at a project and think "OOP is not best suited for this"?

• Why are part-time jobs in programming an anomaly?

  - by Mikle

  I've recently quit my full time developing job at mega-corp, and I decided that I'll look for a part time job. Since then I've talked to half a dozen potential employers, and every one of them had the same reaction when I said the magic words "part-time" - they all closed up and became suspicious. Now, I understand that it might just be me, so as control I asked every one of them what if I were willing to work full time, and they all said I would probably get an offer. My question is two fold: Why, as an employer, would you give up a competent, even great, developer, simply because he wants to work 3 days a week and not 5? How do I sell the story of part time job better? I usually just list my reasons which are that I prefer that balance currently in my life and that I want to work on my own projects, but it leaves them even more suspicious - am I going to start something myself and quit? Am I just lazy?

• External USB hard drive makes noises when the computer is turned off

  - by Amir Adar

  I have an external USB hard drive of 500GB. I can't tell what model it is exactly, as nothing specific is written on it and I don't have the box anymore. I use it as a backup disk. It works absolutely fine when the computer is turned on: no problems with writing or reading, and everything is done in dead silence. However, if I turn the computer off and the disk is still connected, it stays on and makes clicking noises. For that reason I only connect it when I need to back up or restore. Does that mean there's a problem with the disk, or with some preferences in the system itself? Or something else?

• How to customize system preferences settings for all users

  - by user3215

  Does anybody know how to apply a customized user settings to other existing or new users?. Something like a customized preferences settings for system wide so that everybody posses those settings and below will explain in clear what I actually ment. On every machine I will install the following: Eclipse Mysql Query Browser and Admin Mysql Workbench Oracle VirtualBox Thunderbird ----------- ----------- ----------- If I install them by apt, this will automatically create shortcuts in Applications but when I build them from source or extract the tar ball, I will have to add New Item at it's relevant place going to System-->Preferences-->Main Menu to make them available as a shortcuts and this settings are applied only for the account I login and perform them. How could I make this preferences settings for complete system wide which applies for all users? or if there is a way to apply a customized user settings to other users will also be ok. Any hint please? Thank you!

• Looking for a Python UI library comparable with Windows Forms [on hold]

  - by Mitten

  I am looking for a Python UI library which I could use to develop a desktop GUI comparable to what can be done with .NET Windows Forms. I have no previous experience programming UI in Python, so I would rather choose (if there is a choice) something simple. The application I am building would be a document oriented - rich texts, lists and grids, I don't expect to use much graphics - mostly formatted texts. Any pointers, and if there is more than one major GUI library available for Python - how could I quickly test them to see which one is a better fit for my needs?

• Computer vision algorithms (how is this possible?)

  - by Maxim Gershkovich

  I recently stumbled across a company that has created what appears to be a computer vision technology that is capable of detecting shoplifting automatically and alert its users. LINK Watching some of the videos and examples provided by the company has left me completely baffled and amazed as to how on earth they may have achieved this functionality. I understand that no-one here will be able to tell me exactly how this may have been achieved but is anyone aware - and could point me to - research in this field or alternatively perhaps provide details as to how something like this could be implemented or guidance of where one might start? My understanding was the computer vision algorithms were many years away from being this sophisticated. Is this sort of application really possible? Anyone willing to hazard a guess at how they achieved this?

The search box on synaptic is also missing. It has something to do with module named axi. I think the both are related.

• Buddypress with bbpress: Showing latest topics on front page

  - by MadsMadsDk

  I'm doing a wordpress solution with BuddyPress and bbPress, where I need to display the five newest topics on the homepage, as if it was blog-entries, but it seems kind of hard to accomplish. I'm figuring I gotta do something with the activity stream, but it seems like the stream is based on the user who is currently logged in, which is not what I want. So what should I do? Use a nifty plugin that does the trick (maybe someone knows a plugin I don't know of, as I've already tried the bbPress Latest Discussion plugin) Hardcode a forum-activity loop into the page-template file, using the is_front_page() function? Is there a forum-activity hook, that display the latest forum topics sitewide? Thanks in advance

• Literature in programming and computer science

  - by Peter Turner

  I hope, gentle programmers, that you'll forgive me for not asking a "Soft Question" on theoreticalCS.SE and asking this here. It has recently come to my attention that bigendian came from Jonathan Swift's Gulliver's Travels. I was pretty surprised when listening to the book on my commute to hear something I'd only heard before in Comp Sci / Engineering classes. I thought it was some sort of nouveau-politically incorrect piece of holdover jargon like Master and Slave drives or Polish Notation. Are there any other incidents, not of politically incorrect jargon, but of literature influencing aspects of computers, programming or software development?
